BATH-HEATER.

Specification of Letters Patent. Patented July 2'? 1915 Application filed January 22, 1915. Serial No. 3,825.

To all whom it may concern Be it known that I, EDWARD ALEXANDER CLARK, a citizen of the United States,;residing at Norfolk, Norfolkv county, Virginia, have invented certain new and useful Improvements in Bath-Heaters, of which the following is a specification;

This invention relates to a bath heater for use in bath rooms provided with: some H a hood supported by plate 7 and inclosing manner of water supply but with no gas supply or furnace or other heat supply, and is designed for the employment of a burner in heating the water and the atmosphere.

The invention will be readily understood from the following description taken in connection with the accompanying drawing in which Figure 1 is a front elevation of an apparatus illustrating my invention, part appearing in vertical longitudinal section in the plane of line a of Figs. 2 and 3: Fig. 2 a vertical transverse section of the upper portion of the apparatus in the plane of line 7) of Figs. 2 and 3: Fig. 3 a plan of the pipe-supporting saddle; and Fig. 4 a plan of the bunched pipe.

In the drawing :-1, indicates the basepiece: 2, heaters supported thereby and illustrated as oil heaters: 3, the burners of the heaters, the same being of the character known as the blue-flame type, being designed for the production of the blue heating flame instead of the yellow illuminating flame: -"l-, radiating drums disposed above and around the burners: 5, large openings in the upper ends of the drums: 6, legs secured to and projecting upwardly from the base to a point somewhat above the tops of the drums: 7, a plate supported at some distance above the tops of the drums by the upper end of the legs: 8, a pair of large openings in plate 7, one above the open top of each of the drums: 9, a perforated saddle secured to plate 7 at its center of length: 10, apertures extending through the body of the saddle: 11, a bunched coil of heating pipe, of oblong general form, in case two radiating drums are employed, this coil resting on the saddle and projecting endwise therefrom over the openings 8, the coil being in the form of a number or mass of convolutions of the pipe bunched together: 12, the inlet end of the heating pipe: 13, a flexible pipe, as a hose, connected with the inlet to the heating pipe, and to be of such length as to permit it to be connected With such faucet or other fixture as is to supply the heating pipe with water to be heated: 14,

a detachable coupling on the end of flexible pipe 13-to permit that pipe being connected pipe, as a hose, connected with outlet pipe 10 and adapted to lead to the point where theheated water is to be delivered: and 17 the coiled heating pipe.

The heating pipe when disposed in the heater is not provided with systematic passages upwardly through it for the heated gases from the burners but constitutes an unsystematic bunch. The pipe is to be coiled systematically, in layers one above the other, and also in layers one within the other so that the entire heating coil represents a mass of the coiled pipe. Then, by apply ing irregular condensing pressure at the sides of the coil its convolutions become bunched in an unsystematic manner so that the gases seeking to pass upwardly through the mass of pipe require to follow such tortuous passages as they may find among the disordered coils, the result being that the gases move sluggishly through the spaces between the pipe elements and have plenty of time in which to give up their heat to the water within the coils of the pipe.

Assuming an unheated bath room in which there is a supply of water available, as from a water service under pressure or from an elevated tank, flexible pipe 13 is to be connected with the faucet for such supply, by means of coupling 14, which may be the usual rubber cup to be forced over the nose of the faucet. Flexible pipe 16 is to lead to the wash-basin or bath tub or other fixture which is to receive the heated water.

The burners having been lighted, the radiating drums become heated and radiate heat into the bath-room. The hot products from the burners go up through the openit add to the Warming of the bath-room, and heat the Water permitted to pass through the bunched heating pipe. The exemplification sets forth two of the burners and drums, with bunched heating pipe of appropriate oblong form, but there may be a greater or less number of the burners and drums, with a corresponding appropriate form for the bunch of heating pipe.

I claim A bath heater comprising, a base piece, a burner supported thereby, an open-topped radiator drum disposed above and around the burner of the heater, a plate supported a distance above the drum and provided with an opening above the opening in the top of the drum, a perforated saddle sup ported by the plate, a bunched coil of pipe supported by the saddle and presenting itself above the openings in the plate and drum and adapted for connection With a source of cold Water supply and hot Water delivery, and a hood supported by the plate and inclosing the coil, substantially as set forth.
